Description

Wire saw device for excavator

The present invention relates to a wire saw device for an excavator, and more particularly, to a wire saw device for an excavator that is mounted on an excavator to cut rocks, gemstones, concrete, metal, etc. according to specifications according to uses and applications.

In general, stones processed through the extraction of raw stones are widely used as construction materials for buildings or civil works in the construction field, for example, as products such as wall surfaces or road boundary stones or sidewalk blocks or building floors of buildings. processed and used.

These stones are collected in a bulky rectangular shape by a business operator who has obtained a forest damage permit in Seoksan, and transported to a stone processing company. It is also provided after surface processing.

As a method of collecting raw stones from a stone mountain as described above, a jet burner sampling method using a jet burner, a perforator and gunpowder, and a wire saw, a perforator and a wire saw collecting method using a gunpowder are examples.

In the above, the jet burner extraction method uses equipment such as an excavator to remove earth and stone, blasts the raw stone (rock) using an air compressor and a perforator (hole drill), fills the gunpowder, and then blasts it. The method of collecting the raw stone and the formation of the rock, determine the size of the stone, set fire to an air-compressed crater using oil and cut both sides in the longitudinal direction of the rock while burning the stone, then cut the uncut back and bottom There is a method of blasting by drilling blast holes vertically and horizontally with a silver rock drilling machine (equipment for drilling blasting holes), inserting gunpowder into it, and blasting by drilling and blasting according to the size of the slabs in large chunks, and then subdivided again.

Since this jet burner sampling method requires the use of a large amount of diesel, there are problems of air pollution and increased cost, large equipment and compressor facilities must be installed separately, and a situation in which enormous noise is generated and high-pressure heat is generated. There is a big environmental problem, such as a large amount of dust generated by scattering of stone powder by air pressure.

On the other hand, in the above-mentioned wire saw sampling method, the size of the stone (rock) is determined, the vertical and horizontal drilling is performed with a longitudinal drilling machine, and the vertical and horizontal holes are punched in a "B" shape to make a long hole for the wire saw (saw line). After passing it, it is cut by rotating it while pulling it with a machine that pulls both ends, but the back and bottom of the uncut stone are drilled and blown up with gunpowder.

This wire saw cutting method has advantages such as minimizing environmental problems and noise generation, not using diesel (oil), and suppressing scattered dust, but it takes a lot of time to collect due to poor working conditions and cutting efficiency. There is a problem being

In particular, the above-described wire saw method has the inconvenience of installing a separate fixed pulley in the direction to be cut on the raw stone for cutting. have.
